cluster.conf.new: Permission denied

[mfaure]

Hello,

I'm trying to setup Unicast and modifying /etc/pve/cluster.conf with the instructions from http://pve.proxmox.com/wiki/Fencing#General_HowTo_for_editing_the_cluster.conf, but I can't copy the file:

# cp /etc/pve/cluster.conf /etc/pve/cluster.conf.new
cp: cannot create regular file `/etc/pve/cluster.conf.new': Permission denied

I can't even create a single empty file

# touch dummy-file
touch: cannot touch `dummy-file': Permission denied

Here are the rights on the files:

# ls -al

drwxr-x---  2 root www-data    0 Jan  1  1970 .
drwxr-xr-x 91 root root     4096 Dec 28 10:32 ..

What am I missing ?

for background, see http://pve.proxmox.com/wiki/Proxmox_Cluster_file_system_(pmxcfs)

=> without quorum, you cannot write to /etc/pve

This thread is very old but I ran into the same issue and I don't see a viable solution for this thread so I will post my solution in case someone has same issue and even for my future self .

In proxmox7 the /etc/pve/ directory is lock by proxmox so no actions can be made.
to unlock it

systemctl stop pve-cluster
# At this point I think we can directly modify /etc/pve/corosync.conf
# but I will follow the suggested Proxmox wiki procedure
cp /etc/pve/corosync.conf /etc/pve/corosync.conf.new
cp /etc/pve/corosync.conf /etc/pve/corosync.conf.bak
nano /etc/pve/corosync.conf.new
mv /etc/pve/corosync.conf.new /etc/pve/corosync.conf
systemctl start pve-cluster

I hope it helps

This is totaly wrong.
After you stop the cluster there is nothing to edit in /etc/pve

To modify corosync file :

nano /etc/corosync/corosync.conf

once the modifications have been made :

systemctl restart pve-cluster
